What is it called when water vapour turns into liquid water?

Particle Theory is an explanation of why matter behaves the way it does. There are 5 majors points in this theory. Name one of the five.
1. All matter is made up of tiny particles.
2. The particles are always moving.
3. There is space between all particles.
4. Adding heat makes particles move faster.
5. All particles in a pure substance are the same. Different substances are made up of different particles.
In H2O, what does the two mean?
Two Hydrogen Particles
What happens to molecules when they change from a liquid to a gas?
They speed up and move further apart
What are the states of Matter?
Solid, Liquid, Gas
What are three of the 6 ways of changing states?
Melting, Freezing, Evaporation, Condensation, Sublimation, Deposition
Is Salt a pure substance or a mixture?
Pure Substance
Is it possible to fully make particles stop moving when made colder or frozen? Yes or No
No

Which of these are incorrect?
Melting: When a solid changes into a liquid.
Freezing: When a liquid changes into a solid.
Evaporation: When a liquid turns into a Gas.
Condensation: When a Gas turns into a liquid.
Sublimation: When a gas turns into a solid.
Deposition: When a Gas turns into a solid.
Sublimation: When a solid turns into a Gas.
